Adipex (phentermine) is a drug that helps you lose weight by reducing your food cravings significantly. This medicine is supposed to be combined with a healthier diet and regular exercise to make sure it works for you. Otherwise the effects you get may not be so significant. Adipex should taken about 30 minutes before having a meal, and you will need to make sure this is at least 10 hours before going to bed, as otherwise sleep problems may be experienced. At the same time Adipex may cause drowsiness, so you will need to be very careful if you need to perform a hazardous activity. Make sure you know exactly how this drug affects your balance and wellbeing before getting engaged into any activities of that kind. Your health care provider is supposed to know as much as possible about any health problems you have, such as problems with your thyroid, arteriosclerosis, high blood pressure, anxiety disorder, heart disease, seizure disorder, glaucoma, a history of drug or alcohol abuse, or diabetes, as they may affect the dose you are prescribed quite significantly. To make sure your treatment is safe and efficient you will need to follow all the recommendations of your doctor.
